we know that

The equation of a vertical parabola in vertex form is equal to

$y=a(x-h)^{2}+k$

where

(h,k) is the vertex

if ----> the parabola open upward (vertex is a minimum)

if ----> the parabola open downward (vertex is a maximum)

case A) $y=-x^{2}+5$

In this problem we have

the vertex is the point (0,5)

a=-1

therefore

the parabola open downward (vertex is a maximum)

The graph with its corresponding equation in the attached figure

case B) $y=\frac{3}{2} x^{2}-4x$

convert to vertex form

Factor the leading coefficient

$y=\frac{3}{2}(x^{2}-\frac{8}{3}x)$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$y+\frac{8}{3}=\frac{3}{2}(x^{2}-\frac{8}{3}x+\frac{64}{36})$

Rewrite as perfect squares

$y+\frac{8}{3}=\frac{3}{2}(x-\frac{4}{3})^{2}$

$y=\frac{3}{2}(x-\frac{4}{3})^{2}-\frac{8}{3}$

In this problem we have

the vertex is the point $(\frac{4}{3},-\frac{8}{3})$

$a=\frac{3}{2}$

therefore

the parabola open upward (vertex is a minimum)

The graph with its corresponding equation in the attached figure

case C) $y=-x^{2}+2x+4$

convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-4=-(x^{2}-2x)$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$y-4-1=-(x^{2}-2x+1)$

$y-5=-(x^{2}-2x+1)$

Rewrite as perfect squares

$y-5=-(x-1)^{2}$

$y=-(x-1)^{2}+5$

In this problem we have

the vertex is the point (1,5)

a=-1

the y-intercept is

remember that the y-intercept is the value of y when the value of x is equal to zero

therefore

the parabola open downward (vertex is a maximum)

The graph with its corresponding equation is not in the attached figure

case D) $y=\frac{1}{2} x^{2}+2x+3$

convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-3=\frac{1}{2} x^{2}+2x$

Factor the leading coefficient

$y-3=\frac{1}{2}(x^{2}+4x)$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$y-3+2=\frac{1}{2}(x^{2}+4x+4)$

$y-1=\frac{1}{2}(x^{2}+4x+4)$

Rewrite as perfect squares

$y-1=\frac{1}{2}(x+2)^{2}$

$y=\frac{1}{2}(x+2)^{2}+1$

In this problem we have

the vertex is the point (-2,1)

$a=\frac{1}{2}$

therefore

the parabola open upward (vertex is a minimum)

The graph with its corresponding equation in the attached figure

case E) $y=-2x^{2}+4x+3$

convert to vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-3=-2x^{2}+4x$

Factor the leading coefficient

$y-3=-2(x^{2}-2x)$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$y-3-2=-2(x^{2}-2x+1)$

$y-5=-2(x^{2}-2x+1)$

Rewrite as perfect squares

$y-5=-2(x-1)^{2}$

$y=-2(x-1)^{2}+5$

In this problem we have

the vertex is the point (1,5)

a=-2

the y-intercept is

remember that the y-intercept is the value of y when the value of x is equal to zero

therefore

the parabola open downward (vertex is a maximum)

The graph with its corresponding equation in the attached figure

case F) $y=\frac{1}{2} x^{2}+3$

In this problem we have

the vertex is the point (0,3)

$a=\frac{1}{2}$

therefore

the parabola open upward (vertex is a minimum)

The graph with its corresponding equation is not in the attached figure

therefore

the answer in the attached figure
